Initializes a new instance of the
public InstancedBinding(ISubject<object> subject, BindingMode mode, BindingPriority priority)
This constructor can be used to create any type of binding and as such requires an
ISubject<Object>as the binding source because this is the only binding source which can be used for all binding modes. If you wish to create an instance with something other than a subject, use one of the static creation methods on this class.
